Budget requirements vary by industry, funnel and competitive intensity, but many advertisers need several thousand dollars per month to collect statistically useful conversion data; smaller budgets can still work if campaigns are tightly targeted to high-intent keywords or remarketing audiences. Prebo Digital designs spend strategies to prioritise profitable channels and scale when unit economics support it.
For eCommerce campaigns the focus is typically on Shopping, dynamic remarketing and ROAS-driven bidding tied to LTV, while B2B emphasises lead quality, account-based targeting, longer attribution windows and CPL/CPA optimisation. In both cases measurement, funnel optimisation and cross-channel attribution are prioritised to ensure spend drives revenue, not just clicks.
Prebo Digital implements clean data pipelines using GA4, Google Tag Manager, and server-side tracking, and ties platform data to on-site conversions and offline events where applicable to reduce attribution bias. Multi-touch attribution models and consolidated reporting are used to align spend with revenue and lifetime value rather than platform-reported last-click metrics.
Prebo Digital offers end-to-end Google Ads services including account audits, campaign strategy and setup (Search, Shopping, Display, Video, Remarketing), bid and budget management, conversion tracking implementation, and ongoing performance optimisations focused on revenue outcomes.
Time to profitability depends on product margins, funnel conversion rates, tracking accuracy and budget; an initial data-collection and learning phase commonly takes 4-8 weeks, with structured optimisation and scaling typically assessed over several months. Prebo Digital focuses on iterative testing and measurement to improve profitability rather than short-term traffic metrics.

How to compare proposals
How much do online marketing services cost in the United States depends on four core factors: scope (channels and tactics), contract model (hourly, retainer, project, or percentage-of-ad-spend), provider experience, and measurement complexity (server-side tracking, GA4, cross-platform attribution). This article breaks down typical pricing ranges, sample budgets for Shopify and B2B SaaS businesses, and how to align spend with profitability goals rather than vanity metrics.
For a small Shopify store doing $5k/month revenue, a $1,000/month retainer focused on CRO and ads might be reasonable. For an enterprise B2B SaaS product requiring multi-touch attribution, server-side tracking, and custom dashboards, initial project fees can exceed $30,000 with monthly ongoing retainers of $8,000-$20,000. All figures are estimates for US-based engagements and should be validated with proposals.

| Scaling ecommerce brand | $10,000-$100,000 | $4,000-$12,000 | $14,000-$112,000+ |
| B2B SaaS (mid-market) | $5,000-$50,000 | $5,000-$15,000 | $10,000-$65,000+ |

When assessing proposals, focus on measurement and outcome clarity. Ask for: a) baseline metrics and assumptions (traffic, conversion rate, AOV), b) proposed tests and timescales, c) attribution approach (last-click vs multi-touch), and d) reporting cadence with raw data access. Prefer partners that design work to improve profitability (CAC, LTV, MER) rather than just increasing impressions or clicks.
Example A - Shopify DTC brand: baseline AOV $80, conversion 1.5%, monthly ad spend $20,000. A structured CRO + server-side tracking project priced at $8,000/month that improves conversion to 2.0% reduces CAC materially - this is the type of spend designed to pay back within a few months if LTV supports it (all numbers are estimates for illustrative purposes in the United States).
Example B - B2B SaaS: $50,000 annual contract value (ACV), multi-touch sales cycle. Investing $12,000 one-time to implement attribution and pipeline analytics can reduce wasted spend and improve qualified lead quality, lowering effective CAC per closed deal. Again, specifics require an audit.
